I used ASUS Vivobook x540ya since 2 years.and I can say that good product from asus.it is very smoothly working during any type of work.
Although I give only 2 star for this product.i am explaining why it is.
After using 1 years, laptop has crashed its speakers and sound stopped working.so more westage of money I have to do.also there are working upto windows 9 operating system.i want to install windows 10 in my laptop.but some error has displayed and not worked.
I am not happy too much with this product.
